Prince William and Kate Middleton often appear very stoic while in public together, but the couple recently broke from tradition in a rare display of affection.

While being awarded the gold Blue Peter badges for their campaign work on mental health issues affecting children, Kate looked over at William at one point and patted his knee. The pat was quick — but it was sweet and affectionate.

Some royal watchers are wondering if Will and Kate have inadvertently taken notes from the newly engaged couple.

“It is actually simply is a matter of preference for each couple,” royal etiquette expert Myka Meier told the Huffington Post. “Every royal is clearly trusted to make their own judgment calls to what they think is appropriate.”
